Could not get lock Resource temporarily unavailable

apt 安装软件时遇到下面错误

E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/) is another process using it?  

解决方法:

1. 删除 lock file

   sudo rm /var/lib/apt/lists/lock

2. 把cache中的lock file也删了

   sudo rm /var/cache/apt/archives/lock
   sudo rm /var/lib/dpkg/lock

完成
